y IMPROVEMENT IN STEERING APPARATUS.

The Schedule referred to lthere Letters Patent and making part ofthe sama Be it known umm, Dkvm DE naves, of New Orleans, in the parish of Orleans and State of Louisiana, have inventedan Improved Stern and `Steering Apparatus for River Steamers; and I' do hereby de-v clare the followingto be a full and exact description of the same, reference being had Vto the accompanying drawing making part of this specification.

Figure 1 is an elevation and partial section of my` improvement. l 1

\ Figure 2apperspcctive View lof the same. i

Y Figure 3, a plan of the metallic protecting-shoe.

Like letters designate corresponding parts in all the to, when headed down stream, in' rivers with strong currents, thuse'ecting a great saving of ltime and i expense in makiuglandiugs on ordinary trips, and. also, incase of re or otheruaccidents, to open a better avenue of escape for the passengers.

The landing of a boat, with the bow up stream,` in making down tripsis.w`ell known to consume a large `portionof valuable time, andit can 4be shown, by re'- `ports of `rec'ent disasters on our rivers, that a large percentage of the loss of life has been occasioned by the pilots not being able -to land boats of ordinary u In the usual manner of constructing boats.7 no after-castle is provided, and any attempt to back f in to sliorenwouldincvitablyvcrush the rudder if the y bank was low or shelving, 'andboth rudder and'afterguard if the bank was high. j i, In the present inventionI obviate all this by fur` `n'ishing` .the `boat withza complete after-castle, provided with bits, chocks, `capstan-lines, 85e., and also `a complete protection for the rudder.

Description, In the drawing# A is the hull, and f y B the main deck, projecting beyond the hull to form '.lhis deck projects out over the rudder at'the stern,

and isstrengthened by asystem of fan-tail sponsin'g,

i F, built in with the hull, and planked over in a man? ner similar to that shown in thedrawing.

The kelson a and stern post b of the vessel are framed together, and rest, atthe point of junction, in metallic plotccting-shoe,'0, `where they are re-' a tained bymeans of bolts e e e, orotherequivalent de- Vrice. lhis arrangement is shown, enlarged, in fig. 3..

p `The `shoe O Iis prolonged,'to` `form a; solid beak, into which isstepped-thefbot of the ruddcrstock,`the

hang the beak of the shoe, as shown.

lhe rudder-stock has also a bearing in the strap d, which is attached to the stern-post, and carries on its upper end a horizontal sheave, E, around which the tiller-rope' or chain s is rove two or more times, and tllen carried forward, in the usual manner, to the. pilot-wheel. Y

The substitution of the sheaveE in lieu .of the er.v

dinary tiller, enables the pilot to lay the rudder around .against the side of the vessel out of danger,whichhe could not possibly do with aytller. v

Should the bank against which the boat is to land be low or shelving, the blade of the rudder is turned around out of the way, and the shoe O strikes the bank, thus protecting the rudder-stock from injury.

Shouldthe bank be high, the main' after-guard,V

which is so braced by the system of sponsing F asv to possess equal strength with the bow, or nearly so,

will strike and `eiectually preserve theI rudder from injury y Thejudgment of the pilot must, of course,'be exercised in landing, so that he may know whether it will be necessary to la;7 the rudder alongside or not,

and, if necessary, to do so at the proper moment..

The tiller-sheave E and tiller-rope s are situated below the main deck B, out. of the way, and safe from injury and obstruction.

It is to be understood that the arrangement of the several parts herein described is to be considered solely Yiu Arelation to the purpose of, this invention,A

namely, to so construct the stern of' a steamboat that it can be landed, stern foremost, without injury to itself orto the rudder from striking the wharf or grounding, and so that the same facility for embarking and `disembarking may be afforded, Without hindrance or obstruction, as when landing at the bows, and I disclaim the arrangemennexcept as a whole, to effect 'this purpose. y

What I claim as myinvent-ion, and desire to secure byLetters Patent, isi The arrangement, asa whole, of the tiller-sheave E, under the main'deckB, within and protected by the projecting stern-guard F, and theI rudder D, protected beneaththe said stern-guard, and overhanging the shoe C, when also, it is arranged to turn forward against the sides of the steamboat, so as then to' b e protected .bythe said shoe, as and for the purpose herein speciiied. j v
